WHAT IT DOES

What sessions_disable_automatic_network does on CyPerf MCP Server

WHY IT NEEDS A POLICY

Why sessions_disable_automatic_network needs a policy

This tool modifies network configuration by disabling automatic IP assignment (likely DHCP) on all network segments within a session. This is a reversible configuration change (it can be re-enabled), making it Write category. The blast radius is medium because disabling automatic IP assignment across all network segments could disrupt active tests or connectivity, but it does not permanently destroy data.
